Inflorescences pleiochasial, whorled, between the petioles of whorled leaves, at the end of branches, 1/3 to 1/2 the size of largest associated leaf, lax, 6 to 12 flowers; peduncle 2-3 cm; bracteoles triangular, ca. 1 mm, with toothed margins; pedicel 4- 6 mm; upper part of flower buds broadened, oval to glandular, green; corolla hypocrateriform, white with red spots on the lobes; tube ca. 15X2 mm, broadened in the upper 1/3, constricted below the throat at the n the style head, pubescent inside with anthers (0.5 with rounded apex; anthers apex shortly below the orifice of the corolla tube, base touching the apical appendages of style head; filaments curved, 1/3 the size of the anthers and callous at the upper margin that hides the appendages and with a membranaceous skirt at the base; style ca. 5.8 mm; ovary subglobose, ca. 1 .3 mm, syncarpous only at the base, with a rounded apex; nectariferous disc ca. 0.4 mm high, annular. Fruit not seen. cies were collected only in the Governador Valadares region (Brazilian state of Minas Gerais), in forests located at the Rio Doce Basin and by a single collector. This suggests that the collections were made other collections may place this species at a high extinction risk. Relationships. Rauvolfia pruinosifolia differs from R. grandiflora with a tree height of 10—15 m (there is individual), and there is only one leaf whorl on floriferous branches. It shows strongly anisophyllous the largest associated leaf, with flowers that have corolla lobes to 2.5 mm long. Rauvolfia grandiflora bears more than one leaf whorl on the floriferous inflorescences that are slightly shorter to longer than the largest associated leaf, with flowers that have corolla lobes 4—8 mm long. Moreover, plants of R. grandiflora commonly form shrubs or small Etymology. Individuals of Rauvolfia pruinosifolia present epicuticular wax crystals that occur as al., 1998) have revealed that such wax crystals are not found in any other Neotropical species of R< o a These waxes give the leaf a whitish powdery aspect, chosen for this species. 7.

In Rao’s revision (1956), Rauvolfia sessilifolia and R. weddelliana were kept separate although the author R. sessilifolia. Later, Rao (in sched., Robert 494 ) suggests his intention to synonymize R. sessilifolia under R. weddelliana, after examining the type specimen of R. sessilifolia, which he identified as R. weddelliana. By analyzing the type material and otlier specimens of both species, their continuous morpho¬ logical variation could be verified herein. The 470 Novon 471 Nomenklatura!
